Headings BID and B2H. An apparatus for classifying fibrous material in suspension in a liquid or gaseous stream comprises a housing 13, a fixed sieve 18 attached to the housing, a rotatable sieve 19 concentric with and closely adjacent the sieve 18 with an upper portion projecting above the sieve 18 into an upper zone 14 of the housing, an inlet 15 for the stream of fibrous material communicating with the zone 14, a channel 24 in the housing located outwardly of the sieves 18, 19 and below the upper projecting portion of the sieve 19, and an outlet 26 from the channel for discharging coarse fibrous particles, the apertures in the upper portion of the sieve 19 being larger than those in the lower portion which are in turn larger than those in the fixed sieve. An annular shield 28 is disposed between the inlet 15 and the upper portion of the screen 19. The sieve 19 is secured to a plate 21 mounted on a shaft 20 extending through an inner support 22 of the housing and driven by a belt pulley 42. Clearing blades 23 are rigidly mounted on the support 22 and extend close to the inside face of the rotating sieve 19. Below the sieves 18, 19 and extending around the support 22 is a channel 25 which communicates with an outlet 27 for the discharge of medium size fibrous particles. A conical chamber 16 surrounds the fixed sieve 18 and has an outlet 17 for fine fibrous particles. In operation, the stream of fibrous material is fed under pressure tangentially through the inlet 15. The heavier constituents pass along the cylindrical part of the shield 28 in the direction of the arrows 31 and fall into the channel 24. The remaining fibres are forced upwardly (arrows 32) over the conical part of the shield 28 and pass through the gap (arrows 33) between the housing cover 12 and the upper edge of the shield 28. Coarser constituents of the fibrous material on approaching the upper portion of the screen 19 are forced under the action of centrifugal force towards the inside of the shield 28 (arrows 34) and pass under gravity into the channel 24 to be discharged with the heavy constituents through the outlet 26. The medium and fine fibrous particles flow into the interior of the rotating sieve 19 (arrows 41). The fine particles then flow through the lower apertures of the sieve 19 and through the sieve 18 (arrows 35) into the chamber 16 to be discharged through the outlet 17. The medium sized particles retained by the lower part of the sieve 19 and the sieve 18 flow down (arrows 36, 43) into the channel 25 and are ejected through the outlet 2.

Abstract: 1297693 Colour televisions RCA CORPORATION 4 March 1970 [6 March 1969] 10339/70 Heading H4F A colour television camera system generating a luminance signal Y and unambiguous colour difference signals (R - Y), (B - Y), comprises, Fig. I, a black and white camera 15 viewing the scene 19 via a striped colour filter 17 (Figs. 2 or 3) which would produce by itself ambiguous colour difference signals (R - Y), (B - Y), i.e. the (R - Y) signal for blue is indistinguishable (apart from a 180 degrees phase shift) from that for yellow. This phase ambiguity is removed by projecting the image of a filter 23 (Figs. 4 or 5), carrying alternate opaque and transparent stripes, on to the camera tube. Using the filters of Fig. 2 and 4, the camera tube output signal comprises the frequency spectrum of Fig. 7, the luminance signal, 0-3 Mc/s., being caused by the average value of steps in the output signal, the suppressed carrier side-bands centred on 3.5 Mc/s. being caused by the scanning of filter 17 and giving the colour difference signals in T.D.M. fashion, the frequency Fa at 8 Mc/s. being given by the scanning of filter 23 and the frequency (Fa - Fc) at 4.5 Mc/s. being given by the mixing of Fa with the colour difference signal suppressed carrier. The reference signal at Fc is obtained in generator 29 by beating the signals Fa and Fc together, Fig. 10 (not shown), and is used for the synchronous detection at 35 of the unambiguous (R - Y) signal, and, via 180 degrees phase shifter 39, the synchronous detection at 36 of the unambiguous (B - Y) signal. The difference in width of the opaque and transparent stripes in the filter 23 of Fig. 5 produces a second harmonic beat signal (2Fa 1  - Fc), Fig. 8 (not shown), in the tube output, necessitating a frequency doubler in the reference frequency generator 29, Fig. 11 (not shown). Wide alternate green and magenta stripes can be used in filter 23, Fig. 6 (not shown), and this gives the spectrum of Fig. 9. Frequency doubling of (Fc+Fa 2 ) and mixing with (Fc+2Fa 2 ) gives the reference signal Fc, Fig. 12 (not shown).

Abstract: 1316579 Treating keratinous fibres CIBAGEIGY (UK) Ltd and I W S NOMINEE CO Ltd 16 Sept 1970 [8 Oct 1969] 49542/69 Heading D1P A process for modifying keratinous material which comprises treating the material with a polysulphide of formula where R = alkylene hydrocarbon group containing 2 to 4 C atoms R<SP>1</SP> = H 1  CH 3  or C 2 H 5  q is an integer #1 and either m = o when n = p = o or m = 1; when n = p = 1 and allowing the polysulphide to cure on the material.  Preferred polysulphides have an average molecular weight of #500 and #8000, particularly of #3000 and #5000, and in which R denotes -CH 2 -CH 2 , R<SP>1</SP> denotes hydrogen and m = n = p = 1. From 0.5 to 15% by weight of the polysulphide based on the weight of the keratinous material treated is used. The treated material may be heated to an elevated temperature, e.g. 30 to 180C to accelerate the curing of the polysulphide. The fibres are preferably treated at a pH of 7.5 to 12, and the polysulphide is applied as a solution in an organic solvent or as an aqueous dispersion or emulsion. A catalyst, of 0.1 to 20% by weight of the polysulphide, which may be an inorganic base, a siccative, an.oxidizing curing agent or a freeradical catalyst is used in curing. Examples of the catalyst are sulphur, a mercapto benzothiazole, a dithiocarbamate, a thiuram sulphide, a thiourea, a dialkyl disulphide, a dicycloalkyldisulphide, a diaralkylsulphide, an alkyl xanthogen disulphide or an alkyl xanthate. The polysulphide may be used in conjunction with an aminoplast, a polymeric polymercaptan, an epoxy resin, an acrylic resin or a polyisocyanate and the polysulphide may be used in conjunction with a polythiol ester of formula in which R<SP>2</SP> = an aliphatic radical containing #2 C atoms and preferably a hydrocarbon radical containing #6 C atoms v = #2 and #6 t = 0 or a positive integer such that (t + v) is #6 u is a positive integer of #2. The process is used to impart durable press and shrink-resist to wool fibres, fabrics and garments made therefrom. The material to be treated can consist either wholly of keratinous fibres or of blends of these fibres with synthetic material, e.g. polyamides, polyesters, poly (acrylonitrile) and with cellulosic and regenerated cellulosic material, but generally the material should contain #30% by weight of keratinous fibres.
